How to know if a cat is in heat?

The moment comes when every cat begins its reproductive stage, known as oestrus, presenting unusual behaviour for humans. Oestrus is a stage through which both male and female cats go through, although in the case of young kittens the process becomes much more evident.

If you believe that your cat could be in heat, discover all the information about cats that help you detect symptoms, when this stage begins, how often it repeats, and what care you should give your pet.

What is oestrus in cats?

Oestrus is the reproductive process through which female cats pass each time they ovulate and become receptive to become pregnant. In this stage, the cat has very different behaviour from the usual, even going through a physical change that can be very striking.

After passing the time of heat, the cat is again the same as always, until the next cycle in which it is prepared again to be a mother.

When does a cat start to be in heat?

The first oestrus appears in a cat when it is between 5 and 10 months of age. It happens when the cat reaches puberty, and can be very variable depending on the race, and even its date of birth.

Although oestrus can arrive at any time of the year, it is more common to occur in the spring or summer, specifically between the months of March and October.

Symptoms of a cat in heat


You will notice that your kitten has entered into oestrus when you cat gets much more affectionate, rubbing constantly against humans, and looking for petting at all times.


The cats meow much more when in heat, in a very high tone, in order for male cats hear them. This meow sounds like a moan, being more frequent during the night.

Attempts to escape

Be very careful during heat, because the cats can escape in search of a male. Watch and do not leave the windows open to prevent your cat from getting lost or hurt.

How to avoid the discomfort of oestrus

Although oestrus in cats is a process that usually does not last long, it can be annoying and even dangerous if the cat tries to leave constantly.

To avoid problems, and if you do not want to have kittens, the best option for your pet is sterilisation. This way you will avoid the symptoms of oestrus in your pet and protect your cat from any risk.
